In the drawings, 12 designates the' standard, and 13 the sheet-musicsupport. of a music xrack, of well known construction, the standardbeingsupported in a vertical position by a tripod, and the support 13inclined relative'to'thestandard. 1 v The attachment :of my inventioncom prises a clamp having means for separable engagement withthestandard 12, a shelf 20, and means connecting the shelf with theclamp,sa id parts being so arranged that when the clamp is engaged withthe standard,rthe shelf extendslhorizontally beside the Applicationfiled mm 7, 1928.

standard, as indicated by Figure 1, means being provided for laterallysupporting an accumulation of reserve music, either in sheet, book, orfolio form, deposited on the shelf.

The clamp is adapted to embrace and be contracted on the standard 12, sothat it may be confined at any desired height on the standard. The clampshown by Figures 2, 5 and 6, is an elongated loop including acompressible inner neck portion 1%, bearing on the standard,sideportions l5 projecting from-the standard, and an outer neck portion16, having an car 17, in the sides of which are grooves 18, the purposeof which will be described. A clamping screw 19, havinga shoulderbearing on one of the side portions 15, and a threaded portion engagedwith a tapped orifice in the opposite side portion, as best shownbyFigure 6, isadapted to draw the side portions inwardly, and thuscompressthe neck portion 14 on the standard, so that the clamp ispositively engaged with the standard and is unmovable thereon when thescrew is tightened.

Thezclamp shown by Flgure 8, differs from the clamp above described,only in that the compressible neck portion, designatedby 14a has a freeend which overlaps a side portion 15a and is engagedby the clampingscrew 19.

The clamp shown by Figures 9 and 10 will be described later; The shelf20, shown by Figures 1, 3 and 4, is preferablyja part of a structurewhich is foldable, as indicated by Figure 4, so that it may be reducedto compact form and packed in a suitable container with the rack, thelatter being of foldable construction, as usual. Said structureincludesa shank 21, secured at its lower end to the midlength portion of theshelf and constituting the preferred means for connecting the shelf withthe clamp, and inclined braces connecting the ends of the shelf with theupper end of the shank. The shelf. is transversely divided at 22, intotwo sections, .each having upturned flanges 23 and 24' at itslongitudinal edges. To permit the folding of said structure, theinnerflanges 23 are connected by pivots 25 with the lower end of the shank21, and the braces are composed of lower sections 26, pivoted at 27 tothe flanges 23, and upper sections 28, pivoted at 29 to the lowersections, and at 30 to the upper end portion of the shank 21. The saidstructure may be extended, as shown by broken lines in Figure 4, tolocate the shelf sections in alinement with each other, and folded tolocate the shelf sections and the brace sections parallel with theshank. The full lines in Figure 4 show the structure only partly folded,it being obvious that the folding may be completed to locate the shelfsections parallel with the shank.

To provide a separable connection between the shank 21 and the clamp ear17, I provide, in the upper end of the shank, a slot 32, formed toreceive the ear 17. When the ear is in the slot and the structureunfolded, extensions 28a of the upper brace sections, enter the earnotches 18, as best shown by Figure 7 and lock the unfolded structure tothe clamp. \Vhen the structure is folded, the extensions 28a arewithdrawn from the notches, as indicated by broken lines in Figure 7, sothat the folded structure is separable from the clamp.

The shank and braces are connected with the inner edge portions of theshelf, and are arranged to laterally support, in one direction, reservemusic deposited on the shelf. To laterally support the reserve music inthe opposite direction, I secure to the outer edge of the shelf anupwardly projecting resilient tongue 33, which is normall inclinedinwardly above the shelf and is adapted to bear yieldingly on the outerside of a collection of reserve music on the shelf and conformautomatically to the thickness of said collection, so that either a thinor a relatively thick collection may be clamped and prevented from looseendwise movement between the shank and braces at one side, and thetongue at the opposite side.

\Vhen the structure is adapted to be folded, as described, I connect thetongue by pivots 31 with the outer shelf flanges 24, the pivots 34Lbeing in transverse alinement With the pivots 25 connecting the shelfsections with the shank 21.

The clamp shown by Figures 9 and 10 is also positively engageable withthe standard, and is composed of two independent members 36 and 37,formed to embrace the standard 12. The member 36 is permanently rivetedor otherwise secured, to the upper end portion of the shank 21. Themember 37 is proy ided with an angular slot 38, adapted to receive aheaded stud 39, fixed to the shank. A clamping screw 40 is insertible inan orifice 41, in the member 36, and a tapped orifice 42 in the member37, so that rotation of the screw in one direction clamps the members onthe standard, a

reverse rotation releasing the member 37 and permitting its removal fromthe stud 39, as indicated by Figure 10, so that the shank 21 and theparts supported thereby, are separated from the standard.

The clamp shown by Figures 9 and 10 may be employed when the structurewhich includes the shank, the shelf, and the braces, is not foldable.

It will be seen that each embodiment of the invention includes a shelf,means for detachably connecting the shelf with a vertically extendingmusic-rack standard and causing the shelf to extend horizontally acrossthe standard, the shelf being provided at its inner edge with upstandingsupporting means, such as the shank 21 and the inclined braces, adaptedto laterally support the inner side of a collection of reserve music,and at 1ts outer edge with upstandlng supporting means, adapted tosupport the outer side of said collection, said supporting means formingopposite sides of an endless holding space above the shelf, so that theattachment is adapted to hold music sheets which are longer than theshelf.

It will also be seen that in each embodi ment of the invention theinclined braces and the shank 21 are arranged to cooperate in laterallysupporting the inner side of a collection of reserve music on the shelf20, and the tongue 33 is arranged to laterally support the outer side ofsaid collection. The shank and braces project upward from the inner edgeof the shelf and form the. inner side of an endless holding space abovethe shelf while thetongue projects upward from the outer edge of theshelf and forms the outer side of .said endless holding space.

may project outwardly from the ends thereof.

The compressibility of the standard-embracing clamp and the clampingscrew whereby the clamp may be compressed and maintained undercompression, permit a positive engagement of the clamp with the standard12, so that only one clamp is required tomaintain the shank 21 in aVertical position, and the shelf 20 in a horizontal position.

I claim 1. A reserve music-holding attachment comprising a clamp havingmeans for separable engagement with a music rack standard, and providedwith a projecting ear having notches in its opposite sides, a shankhaving in one end portion a slot formed to receive said ear, a shelfcomposed of two relatively movable sections pivoted at their inner endsto the opposite end portion of the shank, and inclined braces extendingfrom the outer ends of the shelf sections to the slotted end portion ofthe shank, and composed of lower sections pivoted to the inner edges ofthe shelf sections adjacent the outer ends thereof, and upper sectionspivoted to the lower sections and to the shank, and provided withextensions arranged to enter the grooves in the clamp ear, and therebylock the shank to said ear, the shank and braces being arranged tolaterally support reserve music deposited on the shelf, the structureincluding the shelf, the shank and the braces being foldable, todisengage the brace extensions from the clamp ear, and reduce thestructure to compact form.

2. A reserve music-holding attachment as specified by claim 1,comprising also a resilient upwardly projecting tongue, pivoted to theinner ends of the shelf sections at the outer edges thereof, andprojecting upwardly from the shelf, to laterally support reserve musicdeposited on the shelf.

In testimony whereof I have affixed my signature.
